This patch enables: Fn+key hotkeys, keyboard backlight brightness control. Additionally this keyboard requires the LED interface to be initialized before such things as keyboard backlight control work. Signed-off-by: Luke D Jones Reviewed-by: Hans de Goede --- Changes v8-v10 - Remove asus_wmi_send_event and change Fn+F5 to emit KEY_PROG4. The ASUS G14-G15 laptops have a problem with freezes if the user spams this key to trigger asus_wmi_send_event(). It is better handled with a key-bind and daemon. - Change cases of dev_warn to hid_warn. - Remove out-of-scope changes which are better suited as separate patches. --- drivers/hid/hid-asus.c | 123 ++++++++++++++++++++++++++++++++++++----- drivers/hid/hid-ids.h | 1 + 2 files changed, 110 insertions(+), 14 deletions(-) diff --git a/drivers/hid/hid-asus.c b/drivers/hid/hid-asus.c index c183caf89d49..1dfe184ebf5a 100644 --- a/drivers/hid/hid-asus.c +++ b/drivers/hid/hid-asus.c @@ -48,6 +48,8 @@ MODULE_DESCRIPTION("Asus HID Keyboard and TouchPad"); #define INPUT_REPORT_ID 0x5d #define FEATURE_KBD_REPORT_ID 0x5a #define FEATURE_KBD_REPORT_SIZE 16 +#define FEATURE_KBD_LED_REPORT_ID1 0x5d +#define FEATURE_KBD_LED_REPORT_ID2 0x5e #define SUPPORT_KBD_BACKLIGHT BIT(0) @@ -80,6 +82,7 @@ MODULE_DESCRIPTION("Asus HID Keyboard and TouchPad"); #define QUIRK_T101HA_DOCK BIT(9) #define QUIRK_T90CHI BIT(10) #define QUIRK_MEDION_E1239T BIT(11) +#define QUIRK_ROG_NKEY_KEYBOARD BIT(12) #define I2C_KEYBOARD_QUIRKS (QUIRK_FIX_NOTEBOOK_REPORT | \ QUIRK_NO_INIT_REPORTS | \ @@ -332,6 +335,28 @@ static int asus_raw_event(struct hid_device *hdev, if (drvdata->quirks & QUIRK_MEDION_E1239T) return asus_e1239t_event(drvdata, data, size); + if (drvdata->quirks & QUIRK_ROG_NKEY_KEYBOARD) { + /* + * Skip these report ID, the device emits a continuous stream associated + * with the AURA mode it is in which looks like an 'echo'. + */ + if (report->id == FEATURE_KBD_LED_REPORT_ID1 || + report->id == FEATURE_KBD_LED_REPORT_ID2) { + return -1; + /* Additional report filtering */ + } else if (report->id == FEATURE_KBD_REPORT_ID) { + /* + * G14 and G15 send these codes on some keypresses with no + * discernable reason for doing so.
